Dev Tools , count widget build can't be activated

I'm facing an issue in Flutter DevTools (version 2.48.0) within the Performance tab, specifically related to the Rebuild Stats section.
When profiling my Flutter app (profile build) on an Android device (arm64), the “Widget build counts” and “Inactive” buttons in the Rebuild Stats panel appear disabled (unclickable).
I’m unable to press them or view any rebuild statistics for my widgets.
🔍 Steps to reproduce:
Run the app in profile mode.
Open DevTools → Performance tab.
Enable “Track widget rebuilds”.
Start recording, then stop to view the results.
Try to click on “Rebuild Stats” or the “Widget build counts” button → both remain inactive.
💡 Expected behavior:
The Rebuild Stats button should be clickable and display detailed widget rebuild statistics after recording performance data.
⚠️ Actual behavior:
The button stays disabled even after recording widget rebuilds. No rebuild stats are shown.

从 Performance 标签页的 Rebuild Stats 流程开始，使用 Flutter DevTools 2.48.0 和 profile 模式的 Android 应用复现该问题。检查 Track widget rebuilds、recording、Rebuild Stats 和 Widget build counts 状态；完成标准是录制后控件变得可点击并显示重建统计信息。
